ST. LOUIS – The Phillies, on the lookout for bullpen help, will be one of a handful of teams to send a scout to watch free-agent reliever Brian Wilson throw Thursday in Los Angeles.

Wilson, 31, is recovering from Tommy John surgery. He has not pitched since April 2012.

“No stone unturned,” said GM Ruben Amaro Jr., who has spoken to a number of teams about acquiring a reliever.

The price to acquire relief help is high. That’s why Amaro wants a fresh report on Wilson. This will not be the first time the Phils have watched the bearded right-hander, Amaro said.

Amaro was asked if he had real interest in Wilson.

“I don’t know yet,” he said. “That’s why we’ll look at him.”

Wilson reached at least 30 saves with the Giants four times. He led the NL with 48 saves in 2010 and has made three NL all-star teams.

MLB checking Hernandez’s statusThe Phillies have asked Major League Baseball to review Cesar Hernandez’s career record to see if he is eligible for a fourth minor-league option. Most players have three minor-league options (they exhaust one per season) once they are placed on the 40-man roster. Some players who sign at a young age are eligible for a fourth option. According to Amaro, MLB is looking at Hernandez’s time in the Venezuelan summer league in 2007 to determine if he warrants a fourth option.

“It would be helpful if he had the fourth option because we had to protect him when he was so young,” Amaro said.

If Hernandez does not get a fourth option, the Phils will have to keep him in the majors out of spring training next year or risk losing him on waivers.

Hernandez, 23, is a strong prospect at second base. He has recently begun playing the outfield as well, as the team tries to increase his versatility for a possible utility role.
